Standard features include a typical line regulation of 10.5 per cent, load regulation of 1one per cent, and ripple and hold of 100, 150 and 240mVp-p maximum at 12, 24, and 48Vdc, respectively. Input/output isolation is 3kVac, hold-up time is 60mS, and operating efficiency is up to 81 per cent. MTBF (per MIL HDBK 217F) is greater than 123 khours.

Operational features include protection circuitry for over-voltage/temperature and overload conditions, and adjustable outputs. All models are approved to UL 508, UL 60950, and EN60950 and comply with EN55011, EN55022 B, and EN6100 specifications.
